You've heard of dolls that eat, crawl, or even wet a diaper but this one is different. It's the breastfeeding doll. A special halter top comes with the doll. The child wears the top which has sensors sewn at the nipples. When the doll touches the sensors it makes a sucking sound. The doll costs 89-dollars. It also burps and cries, but those sounds don't require contact with the breast.
